The seamless steel pipe for general use is rolled by common carbon structural steel, A514 grade C alloy steel plate, low alloy structural steel or alloy structural steel, with the largest output. It is mainly used as the pipe or structural part for conveying fluid. According to different uses, it can be divided into three categories: a according to chemical composition and mechanical properties; B according to mechanical properties; C according to hydrostatic test. If the steel pipe supplied according to class AB is used to accept liquid pressure, hydrostatic test shall also be carried out. The seamless pipes for special purposes include seamless pipes for boiler, chemical power, geological and petroleum, etc.
Weathering steel plate for welding structure is made by adding metal materials such as chromium, molybdenum, titanium and vanadium to ordinary molten steel. The addition of these materials can form a protective film on the steel surface, which can resist weathering corrosion for a long time. The advantages of weathering steel plate for welding structure: It has very good welding performance and weather resistance, and is widely used in railways, bridges and other areas that need to be exposed to the atmosphere for a long time. Disadvantages of weathering steel plate for welded structure: It has very high requirements on the production process, and the poorer technology can not produce good weathering steel plate, A514 grade C alloy steel plate.
Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous A514 grade C alloy steel plate process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.
